Computer Science (CS) introductory courses that are offered by the Department of Information Systems at the University of Minho (UM), Portugal, seem to abound in non-motivated students. They are characterized by high failure and withdrawal rates and use mainly deductive teaching approaches. Deductive instruction begins with theories and progresses…

This study examined the reliability and validity of Web-based portfolio peer assessment. Participants were 72 second-grade students from a senior high school taking a computer course. The results indicated that: 1) there was a lack of consistency across various student raters on a portfolio, or inter-rater reliability; 2) two-thirds of the raters…

We present a novel approach to the automated marking of student programming assignments. Our technique quantifies the structural similarity between unmarked student submissions and marked solutions, and is the basis by which we assign marks. This is accomplished through an efficient novel graph similarity measure ("AssignSim"). Our experiments…

An applied Information Technology (IT) course that is assessed using pen and paper may sound incongruous but it is symptomatic of the state of high-stakes assessment in jurisdictions such as Western Australia. Whereas technology has permeated most aspects of modern life, including schooling, and more has been demanded of education systems in terms…

This paper presents a quantitative approach to multimodal discourse analysis for analyzing online collaborative learning. The coding framework draws together the fields of systemic functional linguistics and Activity Theory to analyze interactions between collaborative-, content- and technology-related discourse. The approach is used to examine…

Describes a study designed to address the difficulties computer science undergraduates have in learning formal reasoning methods. Computer-based tools providing a mixture of graphical and textual on-screen help were evaluated, and results indicate the tools had a positive effect on the learning process. (Author/LRW)

Describes Hyper Apuntes, an interactive learning environment developed at the University Carlos III of Madrid which teaches students the basic concepts of computer programming. Discusses results of an evaluation of the courseware that assessed its usability and utility and collected suggestions for improving the system. (Author/LRW)

This paper presents an exploratory study about the development of a structural and measurement model for the technological acceptance (TAM) of a web-based educational tool. The aim consists of measuring not only the use of this tool, but also the external variables with a significant influence in its use for planning future improvements. The tool,…
